Added Heat Transfer Calculator

[Shuvra-Da-CodER]

Fixes Issue🛠️

Closes #1657

Description👨‍💻

I have added a heat transfer calculator, which estimates the rate of heat transfer through various materials based on input parameters such as thermal conductivity, thickness, temperature difference, and surface area. This tool is essential for engineers, architects, and students to design efficient thermal systems and understand heat transfer phenomena in different applications.
